5 Walk about 120 meters to Huasheng outlets shopping center

2. Pinghu South China City

3. The place is big, the brand is OK, many. However, international brands may be mainly Colombia and Taiwan; CLARKS\ Cross several.

Deep groove ball bearing theory is not subject to axial force, so it can not be calculated

it is characterized by low friction resistance and high speed. It can be used to bear radial load or combined load of radial and axial at the same time. It can also be used to bear axial load, such as small power motor, automobile and tractor gearbox, machine tool gearbox, general machines, tools, etc

When the radial clearance is increased, the angular contact ball bearing has a certain performance and can bear the combined radial and axial load. When the speed is high and thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of deep groove ball bearings with the same size, this kind of bearing has smaller friction coefficient and higher limit speed. But it is not shock resistant and not suitable to bear heavy load

extended data:

when the inner ring of the bearing is tightly matched with the shaft, and the outer ring is loosely matched with the bearing seat hole, the bearing can be pressed on the shaft with a press, and then the shaft and the bearing can be installed into the bearing seat hole together. When pressing, an assembly sleeve (copper or mild steel) made of soft metal material is padded on the end face of the bearing inner ring, The outer ring of the bearing is tightly matched with the bearing seat hole

when the inner ring and the shaft are loose fit, the bearing can be pressed into the bearing seat hole first, and the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly matched with the shaft and seat hole, the inner ring and outer ring in the installation chamber should be pressed into the shaft and seat hole at the same time. The structure of the assembly sleeve should be able to press the end faces of the inner ring and outer ring of the bearing at the same time

5. Calculation of axial bearing capacity of cylindrical roller bearings
cylindrical roller bearings with rib in inner and outer rings, such as NJ, NUP and NF bearings, are mainly used to bear radial load and certain unidirectional axial load, so these axial bearings can be used as fixed bearings
the axial bearing capacity of these bearings depends on the bearing capacity of sliding friction surfaces between roller end face and ring guide rib, that is, it is determined by the lubrication state between sliding friction surfaces, working temperature and bearing heat dissipation condition. The following experimental formula is used to estimate the axial bearing capacity of the bearing:
FAP = (K1 * C0 * 10000) / N * (D + D) - K2 * fr
where:
FAP is the maximum allowable axial load, kn
C0 is the basic rated static load, kn
FR is the actual radial bearing load, kn
n is the speed, R / min
D is the bearing inner diameter, mm
D is the bearing outer diameter, Mm
K1 is 1.5 for oil lubrication and 1 for grease lubrication
K2 is 0.15 for oil lubrication and 0.1 for grease lubrication

6. Orcas are specially used to transport mines and provide bonus. If you want to mine them, you have to be speechless. At the same time, there is no way to open-pit mining or laser mining. Don't consider whether you can use them or not···

7. Using Beitong K1 mobile game keyboard to play, playing up is also very enjoyable, much more accurate than the touch screen.

8. Orcas belong to the flagship ship. The authority of the Legion hangar in the flagship ship is the same as that in the space station office
as the name suggests, only members of the Legion can access the hangar, so different legions cannot access the hangar even in one fleet. The ship in the hangar can put things. As long as you have permission, you can take out the ship anywhere. The hangar is a place for storing things. When you put the ship into the hangar, the pilot will leave the ship, so the members will not follow
permissions can be divided into two categories: the access representative can view the contents and the access representative can take the contents. Of course, if you can't access, you can't take the contents. This is not clear in a few words. The best way is to apply for a trumpet, then join the Legion and give different permissions to test it in person
it should be noted that the hangar is divided into three types: headquarters, base and others. The headquarters is the office of the space station of the corps headquarters in the Corps information. The authority of this office is independent of the other two and should be set independently. The base is set by the pointer to the members. Different members can set different bases according to the activity location. The base authority is also independent of the other two. Others refer to all hangars except headquarters and base, including office hangar, flagship hangar, laboratory hangar and hangar array hangar
it is better to assign permissions by title, which is convenient for management. Eve in the rights management system is very powerful, you can think about it.

9. First of all, we need a house with a lot of structures. Generally, we want to build houses like castles. Secondly, we need furniture. It's better to make more furniture and put some good ones. Then slowly fold all the wall structures to five levels of reinforcement, which is also the most expensive material in the house. Wallpaper can be bought in the furniture store according to your personal preference. If you do all these well, it's almost the same as that of the construction boss.

10. I suggest you learn from Ta Ando of Japan. First join the construction company, have work experience, and then learn the knowledge of aesthetics. No work experience, no bidding project, no one pays attention to you. Without aesthetic foundation, it is impossible to become a master of a generation.
